JAMES S. PRICE, OF SAME PLACE.

COTTON-PRESS.

SPECIFICATION forming part of Letters Patent No. 502,313, dated August1, 1893.

Application filed June 30, 1892- Serial No. $38,499. (No model.)

To all whom it may concern:

Be it known that I, JOSHUA L. Mo CUTOHEON, of Houston, in the county ofHarris and State of Texas, have invented certain new and usefulImprovements in Cotton-Presses, of which the following is aspecification.

My invention relates to cotton-presses and has particular reference tothat class in which the cotton, either in the form of a continuousfolded bat or otherwise, may be pressed between a stationary and a steamor hydraulic power operated platen.

My objects are to combine in one press the advantages of the quick butnot extremely powerful pressure of the ordinary steam press,

and the powerful but slow pressure of the hydraulic press; and to thisend, my invention consists in the construction and combination tion,illustrating a slightlymodified form of support for the swinging blocks.Figs. 3 and 4 are on a slightly larger scale than the other Similarletters of reference in the several views indicate the same parts.

The frame of the press includes the fixed uprights or standards R R, thetimbers F and connecting plate D at the upper end, and the timbers "S Sat the lower end. Above the frame and held vertically thereon by staysB, is secured a steam cylinder A, the lower flange O of which is boltedto the plate D. The lower end of the piston E is connected to a followerG which, in turn is connected to the platen H, by any suitable means.

L represents the lower platen bolted on the flange or head M of thehydraulic ram N, working in a cylinder Q, the upper end of which hasflanges O P through which bolts pass for securing the cylinder and ramto the timbers S.

The distance between the two cylinders A and Q and consequently betweenthe normal positions of the two platens may be somewhat thereon, andwhich support strong blocks or struts I, the purpose of which willpresently be explained. 7

Instead of the tubes K, I may employ a pair of strap arms as shown at Jin Fig. 4..

The operation is as followsThe two platens being in the position shownin Fig. 1,the cotton to be pressed is placed between them and steam isadmitted to the cylinder A to depress theplaten H and thus partiallydepress the charge of cotton. When the platen H has been depressed tothe proper extent, the blocks I I are swung around until they areinterposed between the timbersF and the upper surface of the platen Heach side of the follower G, and are then in position to firmly supportthe said platen against the powerful upward pressure of the hydraulicram which is then operated to complete the compression of the cotton forbaling.

'Having now described my invention, what I claim, and desire to secureby Letters Patout, isi 1. In a cotton press, the combination with theframe, of two platens independently movable toward each other tocompress the material between their faces, motors separate andindependent from each other for operating said platens, and blocks orstruts adapted to beinterposed between portions of the-frame and theback of one of the platens, for the purpose set forth.

2. In a cotton press, the combination with the frame, of two platensindependently movable toward each other,a motor for each platen, one ofwhich is adapted to impart a quick but light pressure, and the other aslow but powerful pressure, the two motors being onward over the upperplaten and rest with their lower ends on said platen and their upperends against a portion of the frame, substan- I 5 tially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 20th day of June, A. D.1892.
